Hollow shaft AB (4" outside diameter, 3.5" inside diameter) is made of aluminum (E=10x106 psi, G=3.8x106psi) and is fixed at A and attached to a rigid plate at B. One end of the rigid plate is attached to a magnesium rod (a = 14.5 x 10-6 in/in/°F and E=6.5x106 psi) with cross-sectional area A=1.0 in² and length l=12" at point C. If the temperature of the magnesium rod is reduced by 100°F, find the maximum shear stress on the outside surface of the shaft AB.
